Ekosistem mangrove adalah suatu ekosistem yang mampu mendukung kehidupan manusia maupun biota yang berada di sekitarnya. Secara global, ekosistem mangrove diakui sebagai ekosistem yang menghasilkan produktivitas di kawasan pesisir. Lahan basah mangrove berperan penting terhadap fungsi ekologis perlindungan pantai, penyangga salinitas, tempat berkembangbiak (breeding site) organisme dan transportasi nutrisi khususnya di Kawasan Pesisir. Penelitian bertujuan untuk mengetahui keanekaragaman spesies mangrove, keanekaragaman spesies plankton, hidrologi, faktor sosial ekonomi dan kualitas breeding site organisme mangrove. Penelitian ini dilakukan Agustus 2022 hingga Desember 2022 di kawasan pesisir Kecamatan Syiah Kuala Kota Banda Aceh. Stasiun penelitian terdiri atas 2 stasiun yaitu Desa Deah Raya dan Desa Alue Naga. Metode yang digunakan adalah metode Line Transect dengan tiga transek pada setiap stasiun yang dilakukan dengan teknik Purposive Sampling. Purposive sampling yaitu pengambilan sampel berdasarkan pertimbangan kehadiran dominansi mangrove. Analisis data menggunakan Indeks keanekaragaman spesies Shanon-Wiener (Ĥ), indeks hidrologi menggunakan pengukuran faktor fisik kimia, indeks sosial ekonomi menggunakan nilai manfaat langsung (direct use value) serta kuantifikasi nilai jasa lingkungan mangrove, dan untuk faktor fisik kimia menggunakan PCA (Principal Component Analysis). Hasil penelitian menunjukkan bahwa indeks keanekaragaman spesies mangrove tergolong rendah dengan nilai Ĥ=1.924, indeks keanekaragaman spesies plankton Ĥ=2.614 tergolong kestabilan komunitas sedang, indeks hidrologi meliputi suhu berkisar 28,2-29,8⁰C, pH 7,1-7,4, DO 2,9-4,1 mg/L, salinitas 27-20,9⁰/₀₀, kecerahan 30-68,5 cm, kedalaman 88,5-105 cm, indeks sosial ekonomi diperoleh Rp.1.142.280.000/tahun dari 63 responden, faktor fisik kimia berupa suhu, pH, DO, kecerahan dan kedalaman mempunyai korelasi positif terdapat pada komponen utama pertama. Kualitas Breeding Site masih tolerir terhadap daya adaptasi organisme.

Mangrove ecosystem is ecosystem capable of supporting human life and the biota that surround it. Globally, ecosystem Mangrove is recognized as a productive ecosystem productivity in the region coast. Wet land of mangroves play an important role to function ecological protection beach, buffer salinity, breeding sites for organisms and transportation nutrition especially in the Coastal Area. Research aims to find out species diversity mangroves, diversity of plankton species, hydrology , socio-economic factors and quality of mangrove organisms breeding sites. This research was conducted from August 2022 to December 2022 in the coastal area of the Syiah Kuala District, Banda Aceh City. Station study consists on the 2 stations are Deah Raya Village and Alue Naga Village. Method used is Line Transect method with three transects at each station performed with purposive sampling technique. Purposive sampling, namely sampling based on consideration of the presence of mangrove dominance. Data analysis using Index diversity species Shanon-Wiener (Ĥ), index hydrology using the measurement of physical chemical factors, social index economics using the value of direct benefits (direct use value) as well as the quantification of the value of mangrove environmental services, and for factor physique chemistry using PCA (Principal Component Analysis). Research results show that species diversity index Mangrove is classified as low with a value of Ĥ = 1.924, plankton species diversity index Ĥ = 2.614 classified as moderate community stability, index hydrology includes temperatures ranging from 28.2-29.8 ⁰ C, pH 7.1-7.4, DO 2.9-4.1 mg/L, salinity 27-20.9 ⁰ / ₀₀, brightness 30-68, 5 cm, depth 88.5-105 cm, socio-economic index obtained Rp.1,142,280,000/year from 63 respondents, physical-chemical factors such as temperature, pH, DO, brightness and depth have a positive correlation in the first main component. The quality of the Breeding Site is still tolerant of the adaptability of organisms.
